United States Patent 3,319,566 QRGAN PIPES Gerhard J. Beisecker, 4670 Station Road, Erie, Pa. 16510 Filed Oct. 22, 1965, Ser. No. 501,300 5 Claims. (6C1. 84349) This invention relates to organ pipes and, more particularly, to the type of organ pipe having a body, foot, and languet.

Organ pipes traditionally have been fabricated of zinc and tin-lead alloys. These pipes had various disadvantages. It has been discovered that a number of advantages can be had by making such pipes out of aluminum according to the techniques disclosed herein. These aluminum pipes have been discovered to have better tone qualities, as well as to be more economical to fabricate, than the conventional well known pipes.

In accordance with the present invention, aluminum sheets may be rolled into a cylindrical form, joined by extruded aluminum clips, and then handcrafted into organ pipes of high tone quality. The combination of parts disclosed herein is responsible for the advantages set forth.

It is, accordingly, an object of the invention to provide an improved organ pipe.

Another object of the invention is to provide an organ pipe that is fabricated from an aluminum sheet.

Another object of the invention is to provide an organ pipe that is simple in construction, economical to manufacture, and simple and efiicient to use.

Another object of the invention is to provide an organ pipe having improved tone qualities.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

FIG. 1 is a front view of a pipe according to the in vention;

FIG. 2 is a cross sectional view taken on line 2-2 of FIG. 1; and

FIG. 3 is a cross sectional view taken on line 33 of FIG. 2.

Now with more particular reference to the drawings, the pipe shown has a body 10 that is made of a sheet of aluminum that is rolled to cylindrical shape and the edges that meet are attached together along a seam 18. The seam may be made by making a clip that receives the two ends of the aluminum sheet of H-shape and soldering the two end of the sheet to this H-shape.

A sleeve made of a narrow strip of aluminum is attached to the inside of the lower end of the body It) by means of rivets 16. The foot 11 is generally conical in shape and has an open upper end that butts against the end of the tube body 10 and the end of the sleeve 15. Since the foot 11 is made of material that is approximately twice as thick as the body 10, the foot will overlie both the end of the body 10 and the end of the sleeve 15.

The foot 11 has a part of the opening 17 in it, and the upper part of the opening 17 is in the indented part 19 of the body. The languet 14 is fixed to the sleeve and extends around it and terminates adjacent the The cap 12 has a lid 22 on it that may be fabricated to it in a conventional sheet metal fabricating manner. The cap is lined with felt 21 so that the cap can be slid up anddown around the upper end of the pipe to tune it.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. An organ pipe comprising a cylindrical body and a foot,

said cylindrical body comprising a flat sheet of aluminum rolled into the form of a cylinder,

said foot being generally conical in shape, closed at its apex end and having an open end,

means whereby said open end of said foot is fixed to one end of said cylindrical body,

a band of aluminum material inside said aluminum cylindrical body extending around it,

said band having an edge disposed flush with the end of said body adjacent said foot,

the end surface of said foot adjacent said body being substantially thicker than said aluminum sheet,

a languet in said body fixed to said strip,

and an opening,

said opening being disposed in the end of said body adjacent said foot.

2. The pipe recited in claim 1 wherein said foot is fixed to said body by solder.

3. The pipe recited in claim 1 wherein said foot is made of a material containing approximately fifty percent tin and fifty percent lead.

4. The pipe recited in claim 3 wherein said sheet from which said sleeve is made has its ends connected together by means of a soldered seam extending longitudinally of said pipe from one end thereof to the other.

5. The pipe recited in claim 4 wherein a hollow cylindrical cap in the form of a cup is supported on the upper end of the pipe, said cap being lined with a felt-like material and slidably received over the upper end of the pipe whereby the pipe can have its tone adjusted.
